Patent EP-0194090-A3 (EP)
IPC: G06F12/14
Filed: 1986-02-25
Abstract: An architecture security fuse circuit is disclosed for secur­
ing the architecture of a configurable programmable logic 
device. The storage element of the circuit is a floating gate tran­
sistor cell 124. Data stored in the cell is determined by the 
amount of charge trapped within the oxide-isolated polysilicon 
floating gate region. The security fuse is initialized (erased) dur­
ing device fabrication to allow access to device architectural 
data. Such initialization is accomplished by a technique that the 
device user cannot duplicate, via an extra probe pad P21 acces­
sible only during wafer probe. To deter the effects of floating 
gate charge loss which may occur during subsequent fabrica­
tion steps, the fuse circuit is adapted to provide a reduced 
memory cell read voltage, thus providing greater margin 
against thermally defeating the security fuse. A regenrative 
feature is provided to strengthen the erased cell during every 
device «clear» cycle. Once the security fuse is programmed, 
the data defining the device architecture may not be interrogat­
ed or altered, and the memory cell 124 is unchanged by the 
regenerative feature.

Title: Powder dispensing apparatus
IPC: B65B39/04
Filed: 1987-07-31
Abstract: An apparatus for transferring powder from a bulk supply to a container comprising a first conduit extending from the bulk supply to the container, an inflatable annulus (21) made preferably from natural rubber, secured towards the end of the conduit and adapted to enter into air-tight engagement with the wall of a container which can be a bag or sack having flexible walls or a drum or carton having rigid walls. The apparatus is also provided with a second conduit having an opening in the container to allow air displaced by powder entering to escape. The second conduit communicates with an exhaust fan (16) to assist the removal of displaced air. A third conduit is also provided having an opening within the container. This opening is placed in close proximity to the outlet situated within the container of the second conduit. When the exhaust fan operates a stream of air enters the container through the third conduit and passes first through the container causing minimum of disturbance to powder which has been delivered and then through the second conduit. This arrangement prevents powder accumulating in the second conduit. The apparatus preferably forms part of a weighing machine so that predetermined quantities of powder can be delivered accurately into the container.

Title: Magnetic recording media, systems using same, apparatus for use therewith and method of positioning a read/write head adjacent a magnetic recording medium
IPC: G11B5/58
Filed: 1987-08-20
Abstract: Magnetic recording media, and magnetic recording systems using such media, are disclosed which incorporate a light-transmitting optical grating at least substantially coextensive with the magnetic recording area. A second light-transmitting optical grating is associated with the magnetic transducer or read/write head. A moire pattern is produced by light transmitted through both optical gratings, and changes in the moire pattern resulting from changes in the alignment of the optical gratings resulting from movement of the read/write head relative to the media are utilized to provide servo information to keep the magnetic transducer aligned with the magnetic track. Higher magnetic recording capacities may be obtained using such media and systems, since none of the magnetic recording area is used for servo information.

Abstract: This invention relates to a process for the separation of acrylonitrile 
used in the cyanoethylation of glycols to produce a bis(cyanoethylated) 
aliphatic glycol from the resulting glycol which is then reduced with hydrogen 
to produce the corresponding bis(aminopropyl) alkoxy glycol. In this process, 
acrylonitrile or methacrylonitrile is reacted with an aliphatic glycol in 
stoichiometric excess and the acrylonitrile removed from the cyanoethylated 
glycol by reaction with aliphatic primary or secondary alcohol prior to 
effecting the hydrogenation of the cyanoethylated aliphatic glycol in the 
presence of the acrylonitrile-amine reaction product. The reaction product 
then can be separated by conventional techniques such as distillation.

Title: Data processing systems with delayed cache write
IPC: G06F12/08
Filed: 1989-05-25
Abstract: In a dual bus microcomputer system using a cache memory and a cache 
controller, the timing requirements placed on non-cache memory 
components by the cache controller are more stringent than the timing 
requirements placed on the non-cache memory components by the 
microprocessor. A logic circuit operates on the cache write enable 
(CWE) signals, and delays those signals in the event of a cache read 
miss. Delaying the CWE signals relaxes the timing requirements placed 
on non-cache memory components and at the same time does not impact 
wait state parameters for read miss operations.

Title: Sheep growth hormone
IPC: A23K20/168
Filed: 1989-09-26
Abstract: In order to produce relatively large quantities 
of recombinant polypeptides having good ovine growth 
hormone activity which can be used  in vivo  as effective 
substitutes for the natural hormone, a complementary DNA 
(cDNA) sequence coding for a recombinant polypeptide 
having ovine growth hormone activity is provided together 
with a suitable cloning vector, so that the DNA sequence 
and cloning vector are ligated to deploy the DNA sequence 
into the cloning vector to form a molecular clone. The 
vector so formed may include a complete or partial copy of 
the ovine growth hormone polypeptide coding region, 
encompassing the mature hormone, extending past the 3′ 
termination codon. The DNA sequence coding may be 
derived from polyadenylated messenger RNA (mRNA) isolated 
from ovine pituitary glands by treating the mRNA with 
reverse transcriptase in the presence of oligodT primer to 
synthesize first strand complementary DNA (cDNA), 
enzymatically removing the mRNA with RNase H, and 
subsequently synthesising the second cDNA strand with DNA 
polymerase I, and treating the double stranded 
complementary DNA (cDNA) so formed with T4 DNA polymerase 
to create flush (blunt) ended molecules.
